Couching Techniques for Cataract Treatment in Osogbo, South West Nigeria
Abstract
Background: Couching is still being practised in developing countries including Nigeria despite its adverse effects on vision.
Objectives: To find out the different techniques of couching, highlight the unacceptable poor visual sequelae and assess knowledge, attitudes, and practices of subjects.
Settings and Design: Clinic based and prospective observational study.
Methods and Material: Structured interview and clinical examination of consecutive patients was used to obtain information.
Results: Fifteen subjects and 20 eyes of 9(60%) males and 6(40%) females were studied. Age range 60 -90 years and mean 72.4±8.0. Commonest presenting complaints were “I cannot see properly/clearly” 4(26.7%) and “I want to do my second eye so I can see better” 3(20%). Presenting Versus (vs.) Corrected visual acuity (VA) was75% vs 60% blind, 55% vs 45% low vision, and 0% vs 10% normal vision, p= 0.032. Friends and neighbours mostly introduced subjects tocouching (26.7% each). Commonest methods involved using sharp objects/needling 45% and blunt/grooving/rocking methods (30%). Subjects assumed “supine” position 75% of time. Eighty five percent of eyes were done at the coucher’s. Procedure was painful in 73.3%. Only 5 eyes (25%) maintained vision for >10years. Thirteen (86.7%) said “no” to a repeat procedure and 93.4% would advice against couching.
Conclusions: Couching methods used were very crude and archaic with attendant poor quality of vision and dissatisfaction. Public education, affordable and accessible cataract surgical services taken to the rural communities could gradually phase out couching.
